Which coupling on a hoseline will indicate you are headed toward an egress point?

• A. Male
• B. Female
• C. Storz
• D. Threaded

Answer: (A)

Understanding how hose couplings indicate line orientation helps you read where you’re headed on a hoseline. The forward or leading end of the line is the male coupling. It’s the plug-style end that will mate with a female coupling on the next segment or with equipment at the point of egress, allowing quick connections as you advance toward safety. In practice, seeing a male coupling toward the exit tells you you’re moving toward where the line will connect to the final assembly or nozzle near the egress point, enabling rapid break-out if needed. The other options don’t provide that directional cue: Storz is a symmetric coupling and can connect in either orientation, while threaded and female ends describe mating styles that don’t signal the forward direction toward the exit.
